He said Ms Ardern had already made her expectations of her Ministers clear, when he was asked whether Ms Curran was setting the benchmark standard.

"The Prime Minister has made it very public that she did not think that a certain standard had been met, and that's why she took action. That's been known for some considerable time," Mr Peters replied.

It's been two weeks since Ms Curran resigned as the Minister for Open Government and Government Digital Services, and Prime Minister Jacinda Ardern kicked her out of Cabinet, over her failure to disclose a meeting she held in her Beehive office.

Before that, she came under fire for failing to disclose a meeting with former RNZ executive Carol Hirschfeld in response to a written parliamentary question.

Ms Curran remains the Minister of Broadcasting, Communications and Digital Media and the Associate Minister for ACC, and she is the MP for Dunedin South.
